It has been three years since Song Zhong returned to Huaxia. For three years, he worked to make amends for those displaced by him. These are the things he thinks are important.

Hannah's formula, which he hasn't used for a long time. The system is also almost dormant.

He watched his children grow up happily day by day, and this was more important than anything for him.

On this day, Liu Er, who grew up together, came to the door.

"Yell. How do busy people have time to come. ”

Liu Er looked a little down, with a scruffy beard and unkempt hair.

"Busy, busy. In the end of the hard work, not to mention nothing, but also to post money. ”

"How?"

"A while ago, I bought a few cartloads of small canola. Unexpectedly, it rained for more than ten days. It's all rotten. ”

Song Zhong frowned!

"Isn't the car refrigerated?"

Liu Er shook his head! "Refrigeration is also time-limited. Refrigerate for too long, and it will rot quickly when it reaches the customer's hands! Don't think about messing around in this business after that. ”

"I can't see it! You're pretty honest! Isn't there a fresh-keeping spray on the market at the moment? ”

Liu Er shook his head: "Of course there is!" However, they are all chemical products, and their toxicity is greater than that of pesticide residues. Don't dare to use it. ”

"In this case, there is no harmless fresh-keeping spray on the market at present?"

Sixty-two nodded!

"If you can make a fresh-keeping spray that is made of the same material as water, is it very marketable?"

Liu Eryi was immediately interested when he heard this.

"Of course it's good to have this kind of thing! I'm telling you, that's a big business opportunity. ”

"Then I'll take a look! You can also contact your food friends by the way. Three days. Wait for my reply. ”

"Song Zhong! You're not kidding! If you can figure it out, a proper 10 billion market in a year! ”

After sending Liu Er away, Song Zhong began to think about how to make this spray!

"π, how do you make a harmless fresh-keeping spray?"

"Host, since you haven't woken up the system for a long time. The system has automatically gone to sleep. ”

"How do I go out of hibernation?"

"Wake value needed!"

"How do I get wake value? How much does it take to wake up? ”

"As long as someone meditates on the number of sequences of π every day, it will increase the wake-up value. When the wake value reaches 1,000, it will wake up once. Valid for two hours! At the same time, the wake value can be cumulative. At the same time, the awakening value can be exchanged for physical attribute enhancement! Strengthened to a metallic hydrogen physique, requires 100,000 awakening points. ”

"You mean that as long as someone silently recites the sequence of π, they can accumulate awakening points, which will make me stronger!"

"Yes! The higher the host attributes, the higher the fit with the π, and the stronger the π attributes!

Then tell me, how to make a pollution-free fresh-keeping spray! ”

"The system is hibernating! Unable to exercise the order. ”

“3.1415926…… A thousand! ”

"Gain a wake value."

"Xiaomi, adzuki beans! Come here! ”

Song Zhong called the two babies in front of him with a cold face!

"Dad, from today, I'm going to give you an assignment to improve your memory. Spend two hours a day memorizing what is on this piece of paper. Of course, you can also go out and have fun, but you have to ask your friends to read the contents of this piece of paper with you. As long as they recite with you for two hours, you can play for a day. ”

"What should I do if my grandparents blame me?" Millet.

"Just tell them you're working on your memory! You can also bring your grandparents to read aloud together, which can prevent Alzheimer's! Get started now! ”

Xiaomi Xiaodou pulled her father's arm and coquettishly said, "Dad, can I go out to play now?" ”

"No! Unless you promise to find a friend to read aloud with! ”

"Okay!"

"Then go! Start reading now, read it aloud! ”

"3.1415926......" until it disappears into the hallway!

Song Zhong tried to recall the high-pressure form of the most ideal material, water......

Glue binding! Yes, that's it! With π capabilities, there should be no problem making this gel spray!

The most important thing now is to make up 1,000 wake points!

"Hey, Liu Er. How many merchants have you contacted now? ”

"What's the matter, Zhongzi, you made it!"

"This ...... It's pretty much the same. But I need a little cooperation from you! ”

"How to cooperate? Pay? ”

"No, you don't! As long as you recite the sequence of π to 1,000 digits. How many of you are there? ”

"More than 900 people, everyone is very interested in this spray!"

"Then let's get started! Tomorrow, it can be made, only you cooperate well! ”

"Good!" Liu Er looked stunned, but he still did it!

"The wake-up value from Xiaohu is increased by one......

Wake value from Floret is increased by one

The wake value from the Star Eye is increased by one

……

Wake value from Wu Sihai plus one"

Two hours later

"The awakening value from Song Beichen is plus one

The awakening value from Lu Qiuping is increased by 1......

Congratulations to the host! π was successfully awakened!

Take care of the fresh-keeping spray for you right away.

How many tons of demand do you need? ”

"A hundred tons! Divided into 450ml aliquots. ”

"The system prompts, the time is not enough to ......"

"90 tons!"

"Not enough time"

"How many tons can you make?"

"Ten tons!"

"Alright! Start making! By the way, for each wake-up, the duration increases by one hour! ”

Two hours later......

"It's done! A total of 123,000 bottles! Need to ship it for you? ”

"Yes!"

The bottles were neatly stacked in the living room of Song Zhong's house! It's stuffed to the brim!

"Hint! Because it is a high-density colloidal water, as long as you press it for three seconds in a 100 square meter confined space, you can complete the freshness! One bottle can be used a thousand times. It is recommended to charge a cost fee of 10,000 yuan. ”

"Liu Er! Bring someone to pick up the goods! ”

Nine hundred people came to Song Zhong's house!

Since the living room was stuffed, everyone had to wait downstairs!

Send Liu Er as a representative.

"Song Zhong! That's what you call pollution-free fresh-keeping spray! ”

Song Zhong nodded!

"In a 100-flat sealed environment, hold it for three seconds to complete freshness! The price is 10,000. ”

"Ten thousand?"

Song Zhong nodded!

"Then can I buy a bottle and try it first!"

"Yes, next time it's 12,000!"

"Twelve thousand, that's one hundred and twenty. I'll buy a bottle first. How long does it last? ”

"20 days!"

Liu Er went home with a bottle of spray!

Song Zhong looked at the awakening value, and it had already exceeded two thousand!

Mainly from the crazy contributions of the children!

"Who says you don't need good looks? My child's release is a representative of appearance. ”
